Dell HYV3H is a 290W power supply unit designed as a compatible replacement for Dell systems that require the HYV3H module. The unit provides a fixed 290-watt output to power server or workstation components and is intended for restoring or maintaining stable power delivery in supported Dell hardware configurations. The compact form factor and standard connector set make it suitable for straightforward swap-in replacement in compatible chassis.

Advantages

This 290W power supply delivers a consistent single-output power source suited to low- to mid-power server and workstation components. The design focuses on reliability and compatibility with Dell systems that accept this form factor and connector arrangement. Its fixed-output rating simplifies capacity planning and replacement decisions by matching original equipment power specifications.

Suitable for

• Replacing a failed or underperforming PSU in compatible Dell servers or workstations
• Restoring stable power delivery after hardware maintenance or upgrades
• Service and spare-part inventory for IT departments maintaining Dell systems

Key specifications

• Output power: 290 watts (fixed single output)
• Form factor: compatible replacement for specified Dell module form
• Cooling: internal fan for active cooling
• Input voltage: designed for standard AC mains input (region-dependent)
• Connectors: standard system power connector compatible with Dell chassis using this module

How to use

Before installation, power down the system and disconnect it from the mains supply. Remove the failed unit following the chassis manufacturer’s instructions to avoid damage to connectors and surrounding components. Slide the replacement HYV3H module into the designated PSU bay until it seats securely and engage any retention latches. Reconnect the mains power and power on the system, then verify that the system recognizes the replacement and that voltages and fan operation are within expected ranges.

Recommendations

Use the power supply in environments that meet the host system’s specified ambient temperature and ventilation requirements. Confirm compatibility with your specific Dell chassis and system revision before purchase. Keep a record of installed spares and perform visual inspections periodically to check for dust accumulation, secure connections, and normal fan operation.
